UNITED STATES PATENT QFFIGE NICHOLAS BAY, OF SGHENEOTADY, NEW YQRK.

IMPRCVEMENT IN GAGE-CQCKS.

Specification forming part of Letters Patent No. 134,098, dated December17, 1872.

' To all whom it may concern:

Be it known that I, NIcHoLAs RAY, of Schenectady, in the county ofSchenectady, and in the State of New York, have invented certain new anduseful Improvements in Gage- Gocks; and do hereby declare that thefollowing is afull, clear, and exact description thereof, referencebeing had to the accompanying drawing making a part of thisspecification, in which Figure 1 is a side elevation of my improveddevice; Fig. 2 is a central longitudinal section of the same; and Figs.3 to 6 are side elevations of the different parts of said de- V vicebefore being combined.

Letters of like name and kind refer to like I parts in each of thefigures.

The principal object of my invention is to enable access to be easilyhad to the interior of the barrel for the purpose of cleansing the sameor for dressing the valve-seat; and it consists in the device as awhole, when its several parts are constructed and combined substantiallyas and for the purpose hereinafter specified.

In the annexed drawing, A represents the inner section of the barrel,provided upon its outer end with a threaded neck, A, which terminates atits inner end in a square shoulder, a. The outer section 13, having anydesired exterior shape, is provided within its inner end with a threadedopening, which corresponds to and fits over the neck A of the innersection, said parts when thus connected having the usual form of abarrel of ordinary construction. The valve-seat a upon the end-of thesection A is somewhat less in diameter than the contiguous portion ofsaid end, and'at its center has an opening, 00, that, extendinglongitudinally through the center of said section, furnishescommunication with the interior of the boiler. The outer portion ofsection B is provided with a threaded opening that receives acorresponding plug, 0, upon the inner end of which is secured a valve,D, that, when said plug is screwed inward,

impinges against the valve-seat a, and closes the opening through thesame. In order that freedom of action may be secured to the valve, saidpart is provided with a stem, D, which fits into a corresponding openingin the end 'of the plug, and enables either of said parts to rotateindependent of the other. It, now, the plug be screwed inward, thevalve, when brought into contact with its seat, will remain stationaryinstead of revolving upon and abrading said seat. By making said valveof copper or other soft metal, greater durability of parts will besecured and a closer joint produced. A discharge-nozzle, E, extendingradially outward from section B forward of the valve-seat, completes thedevice, which is used in the ordinary manner.

As thus constructed, it will be seen that by removing the outer sectionof the barrel the valve-seat is fully exposed, and, it required, can beeasily dressed oft with a file, by which means great convenience issecured, and less time and expense rendered necessary in keeping thedevice in repair than is usually requisite.

It will be seen that this improvement is equally applicable to any formof cock in which the valve screws down upon its seat, the principleinvolved being the same, whatever the exterior form of the device.

Having thus fully set forth the nature and merits of my invention, whatI claim as new,

The hereinbeforc-described gage-coclqconsisting of the sections A and Band the plug 0, with or without the valve D and 1), when said parts areconstructed and combined substantially as and for the purpose shown.

In testimony that I claim the'i foregoing I have hereunto set my handthis 1st day of November, 1872.

NICHOLAS RAY.
